'CONDUI'I DEVICE FOR TAPEING CANS.

Application filed May 4,

tween the receptacles and the conduit de vices and the object of myimprovement is' to provide simple and eificient means by which an outletconduit as a faucet, may be tapped into and secured by a rigid leakproof connection to aclosedreceptacieof thin metal without having accessto the inside of said receptacle.

The invention consists in the novel construction, adaptation andcombination of parts as will be more clearly hereinafter described andclaimed.

In the accompanying drawings Figure 1 is a View in side elevation of afaucet that is equipped with devices constructed in accordance with myinvention, certain of such devices bemg shown in cross section and afragment of a receptacle to which the fancet is connected being shown incross sec tion. 7

Fig. 2 is a view partly in section and partly in elevation substantiallyon broken line 2, 2 of Fig. 1.

Fig. 3 is a view partly in section and partly in elevation substantiallyon a broken line 3, 8 of Fig. 1, the receptacle being omitted.

Fig. 4 is a fragmentary view in elevation of a receptacle that hasa holeand a slot cut therein preparatory to applying the faucet shown in Fig.1 thereto.

Fig. 5 is a fragmentary view in perspective of the same receptacleshowing the metal adjacent the slot bent outwardly in a suitableposition to engage within a groove on a knob on the end of the faucet.

Referring to the drawings, throughout which like reference numeralsdesignate like parts, the numeral 6 designates a faucet of ordinaryconstruction that is provided with a threaded shank 7 which is adaptedto be Specification of Letters Patent.

connected with any suitable receptacle or conduit from which liquid isto-be drawn off.

The end of the shank 7' has a relatively large knob or head 8 rigidlysecured thereto which head 8 is rounded on its outer side and is flat onits inner side to form an annular shoulder 10. The head 8 is providedwith a spiral slot or groove 11 that is cut entirely through such headand preferably extends from the periphery thereof inwardly in spiralfashion and intersects the shank? at a. point substantially ninetydegrees from the point of beginning.

The head 8' may be screwed onto the end of the shank 7 until its outersurface is flush with the outer end of the shank and may then besoldered or brazed thereon to prevent it from turning. 8 is put onto theshank, a nut 12, a metal washer 13 and a hard rubber or fiberw-asher- 14are placed on such shank 7 in the order named so that the rubber orfiber washer.

14 will bear against the side of a tin or sheet metal container 15 whenthe nut 12 is tightened in the final position as shown in Fig. 1. V

"Thecontainer 15 is prepared for the reception of the faucet by cuttintherein a cylindrical hole 16 of just large enough diameter to fit overthe shank 7 then cutting a slot 17 outwardly from the hole 16, a distance equal to substantially the width of the flange or shoulder 10 andthen bending the metal at one side of the slot 17 outward slightly asshown at 18 in Fig. 5. I

In inserting the head 8 through the hole 16 such head is placedagainstthe outside Before the head of the hole with the outwardly bentportion 18 of metal inserted-a slight distance into the groove 11 andthe head is then turned in the proper direction to cause the bentportion of metal 18 to pass into and through the groove 11 and the headto pass entirely through the hole 16. As the head 8 passes through thehole 16 the metal at the two sides of the slot 17 will necessarily bebent so that it will. leave an opening somewhat larger than that shownin Fig. 5 but when the nut12 is tightenedas shown in Fig. 1 the bentportions will be bent back into their original positions and the metalof the container will be tightly clamped between the washer l and thehead 8 thus forming a liquid tight connection. The

washer 14c will preferably be of slightly larger diameter than the head8.

In removing this device from a can or receptacle the nut 12 is loosened,one of the edges of the metal adjacent the slot 1'7 is bent inwardlyenough so that it will engage within the slot 11 in the head 8 and thefaucet is turned far enough to permit the head to pass out of the hole16.

In inserting the faucet in a closed ca that is full of liquid, as oil,the can will preferably be laid on its side and the hole 16 cut in theuppermost side of the can near the bottom thereof. After the faucet isinserted and the nut 12 tightened the can may be strightened up and thefaucet used in the usual manner to draw off the liquid.

In practice the spiral groove 11 will pref erably be at the uppermostportion of the head 8 and the slot 17 will preferably intersect thebottom of the hole 16 so that the groove 11 and slot 17 will not beopposite each other in the final position.

The invention is shown as applied to a faucet but it will be understoodthat the shank 7 may be any cylindrical member either solid or tubular.

From the above description taken in connection with the accompanyingdrawings the advantages of the construction and of the method ofoperation of my invention will be readily appar nt to those skilled inthe art to which the same relates, but, while I have described theprinciple of operation of the invention together with the device which Inow consider to be the best em bodiment thereof, I desire to have itunderstood that the device shown is merely illus trative and that suchchanges may be made as are within the scope of the following claims.

What I claim is 2-- 1. The combination with a plate of flexible materialhaving a circular hole therein and provided with a slot that intersectssaid hole, of a cylindrical shank adapted to be inserted in said hole,and a head on said shank, said head being of larger diameter than saidhole and having a groove extending spirally from the outer to the innersurface thereof and arranged to permit the passage of the materialaround the circumferenceof said hole whereby said head may be passedthrough said hole.

2. Apparatus of the class described comprising a closed receptacle ofthin flexible metal having a circular hole therein and provided with aslot that intersects said hole, a tubular shank adapted to fit snuglywithin said hole, a head on said shank, said head being of largerdiameter than said hole and being convex on its outer surface andplane'on its inner surface and said head having a groove extendingspirally therethrough from the plane inner surface to the convex outersurface and arranged to permit the passage therethrough of materialsurrounding said hole whereby said head may be passed through said holeby turning the same, and means on said shank for clamping the metalaround the circumference of said hole against the plane side of saidhead.

. In witness whereof, I hereunto subscribe my name this 29th day ofApril, A. D. 1920.
